Giving notes about how quests work, prizes and locations etc. is fine. The game assumes that players freely share information. If I want to make something secret, it'll randomise on a per-player basis.

Dear Chris

It was good to speak to you recently and to find out more about TotL and I must apologise for the delay in contacting you to acknowledge your donation - I’ve been away for a week. However, I can confirm that we have received your very generous gift of £500, gained through the online auction of TotL game elements, to support the work of Practical Action. Attached to this email please also find a certificate of acknowledgement.

This is a fantastic amount to have raised, and I’m so pleased that you have chosen to support our work in this way. Your donation will help provide long-term solutions to the many problems faced by communities in Africa, Asia and Latin America. At Practical Action, we believe that the best way to ensure a better future for the world’s poorest people is to work in partnership with them to develop the means for them to take control of their own lives.

Your support means that Practical Action can continue working in some of the poorest areas in the world, helping local communities find practical answers to overcome poverty. On behalf of these communities, please pass on our very grateful thanks to everyone who donated.

Please do not hesitate to contact me should you wish to find out more about any of our projects. In the meantime, thank you again.
